3D Scanning Sonar Data Collection from a Moving ROV

Background:

MotionScan™ enables the collection of 3D scanning data from an ROV by correcting for motion and position changes of the platform. The solution developed by Teledyne BlueView and Teledyne PDS has been integrated into lightweight ROV specifically designed to display the 3D Scanning Sonar to strategic locations. The light weight ROV was designed by Teledyne Benthos and is instrumented with heading, pitch and roll sensors to correct the data for attitude changes while the ROV is holding position.

The owner of the ROV, IDEA, and Teledyne BlueView’s local Japanese distributor, Hydro Systems Development, Inc. are integrating underwater positioning systems, inertial navigation systems, and USBL to assist with position change corrections of the vehicle.

Solution:

“The ROV with integrated MotionScan 3D Scanning Sonar provides a highly versatile tool that collects high resolution 3D point clouds of areas that were previously inaccessible with traditional means to collect 3D point cloud data”, says Mr. Soutaro Takashima with IDEA. ”The improved deliverables and modularity of the 3D Scanning Sonar provides a highly valuable asset to our company, this is why we invested in the ROV, 3D Scanning Sonar and surface vessel deployment equipment”.

The MotionScan 3D Scanning Sonar deployed on an ROV allows operators to collect 3D point clouds of structures from the seabed to the surface with one tool. The ROV can hold position to conduct scans or traverse with the sonar angled at the area of interest while the ROV is moving by a structure to collect 3D profile data.

ROVs operating in areas with low visibility can see the benefits of the 3D Scanning Sonar with a 3D point cloud of the work site that can be manipulated to take measurements, volume calculations and provide detailed information on the areas of interest. These deliverables can greatly increase the capability of any ROV system for many markets to increase the decision making capabilities on site.
